Step 6: Well, finally here is how to Create a symlink for mount_ntfs
Link NTFS-3G to the system location. In a Terminal prompt:
sudo mv /sbin/mount_ntfs /sbin/mount_ntfs.original
sudo ln -s /usr/local/sbin/mount_ntfs /sbin/mount_ntfs
*i have successfully done upto step 5 but in the last step when i wrote that command it says
in terminal it says :-
-> mv: rename /sbin/mount_ntfs to /sbin/mount_ntfs.original: Operation not permitted
-> ln: /sbin/mount_ntfs: Operation not permitted
note:- i have os x el capitan version 10.11.2 installed in my macbook pro 2015

It works fine for me.
At the beginning, it didn't worked because i wrote the name of my disk wrong (i just replaced space with \040) after that you do Ctrl + O, press Enter to save the modifications and then Ctrl + X to exit.
After that, my volume disapeared and it still didn't work.
So i went back to the terminal and erased the content of the fstab and saved.
I reboot my system and my disk was back again.
I did the command line again (with the good spelling of my drive) and after i went to the utility disk application to unmount my drive and mount it again.
After that, I did a right click on the name of my drive and chose "Find it in the finder" (sorry don't know if it's the real name of this command because i'm french and it's write in french for me ).
I was then able to see my disk again and i put an shortcut on my desk and it was it !
Thank U, i tried hard to find a solution to this problem, U made my day !

I decided to use this app after 2 hours installing NTFS-3G without any positive movements. It seems to work perfectly with my macbook 2015 running El Capitan.
Pros: No comments yes
Cons: It's still quite expensive after even 20% coupon is added.
